Work on the ligtBOX has been shifting from on-site demolition and prep for framing to in-the-shop milling and sanding of the structural glulams that form the exposed frame on the south wall of sliding doors and fixed glass.
As mentioned before the structural glulams will be assembled using Timberlinx post connectors. In order for this to go smoothly on site as the frame goes up, we've been laying out and milling the glulam pieces. This included making a jig that is set up for most of the connection conditions we have.
The jig is made to easily locate the brass bushing that makes for a nice perpendicular 1 1/8" hole in the beam end. A large auger bit attached into a strong electric drill makes for a fairly straight forward holw bore.
The perpendicular bore holes have to be pretty close to perfectly align for the pin connectors to correctly seat, and the jig and brass bushing fitting make this an easy job.
Since the glulams are exposed on both the interior and the exterior we've also taken the time to sand their exposed faces down for a good coating of exterior-grade oil sealant.
